Deleting columns
On the NavBar, click Grades.
On the Grades page, click Manage Grades.
Click the More Actions option.
From the More Options drop down menu, select delete.
Select the check box next to the grade item/items and/or category/categories you wish to delete. Click Delete (this gives you a chance to back out if you really didn’t mean to delete it.)
Click Delete.
You will need to select the items a second time and click delete a second time. After this, you will need to confirm that you want to delete your selection, or cancel.
*Important Note: If your category contains items, those items will remain in the grade book and may need to be reorganized into other categories.
